SPECIFICATION formng part of Letters Patent No. 264901, dated September5, 1882. Application filed February 14, 1882. (No model.)

10 all whom it may concem: O

Be it known that I, CLAUDIUS VERNIAUD, of Quincy, in the county of Adamsand State of lllinois, have invented certain new and useful Improvenentsin Lubricators for Steam Machinery and I hereby declare the following tobe a full, clear, and exactrdescription ot' the same, reference beinghad to the acconpanyin g drawings, formin g apartof this speci--fication, in which- Figure 1 is a vertical sectional view of myinvention, showing its practical application to the steam-pipe of anengine. Fig. 2 is a seetional View of oneof the fittings detached. F g.3 is a cross-seetional view of a condeser having longitudinalcorrugations instead of lateral corrugations, asin the condenser shownin Fig. 1.

Similar letters ot' reference in the several figures denote the sameparts.

This invention consists ot' an improved lubricator for steam machinery,constructed and operated as will be hereinafter full y described, i andpointed out in the claims.

In the accompanyin g drawin gs, A represents the oil chamber orreservor; B, a fitting se-- cured to the upper'part of the said chamberA, having a passage, b, leading into a vertical glass tube, C, andadapted to be opened and closed by means of a valve, D, and havinganother independent passage, b', leading from the said tube G into aglobe-valve, E, connected to the steam-pipe S, which leads to the partof the engine to be lubricated.

B' is another fitting, similar to the fitting B, connected to the lowerpart of the oil-chamber A, and having a pipe, H, connected toit withinthe oil-chamber, and extending up vertically within the clamber to apoint at or above thepassage b of the upper fitting, B, as shown. Thefitting B' has passages c, c', ende similar to the passages I b' I) inthe upper fitting, the passage c, leading into the pipe H, the passagec' leading into the lower end ot' the glass tube C, and being controlledby the valve D, and the passage 0 leading from the glass tube C intoanother globe-valve, E', connected to the pipe S. The connectionsbetween the fittings B B' and the oil-chamber A, the glass tube C, andthe globe-valves E E' are all made air and water tight.

F represents the condenser, from the upper end of which extends a pipe,F', leading into the steam-pipe S, and having a check-valve, V, arrangedin it. From the lower end of said condenser leads a pipe, G, that passesdown into the oil-chamber to within a short distance of the bottomthereof, as shown, beingprovided with a controlliug-valve, K, betweenthe oil-chamber and the condenser.

J represents a plug in the upper part of the oil-chamber, which can beremoved for the filling of said chamber with oil, and I is a pet cock,by which the contents of the oil-chamber can be drawn ofi' when desired.

The oil-chamber being filled with oil and the valves D D' E E' beingclosed, the oiler may be operated as follows: Steam from the steampipe Senters the pipe F', passes the check-valveVtherein, and enters thecondenser F. The valve K is then opened more or less,

so as to allow the water of condensation to pass to the bottom of theoil-chamber. The valve D may then he opened, so as to permit the oil topass through the passages b b' into the glass tube 0 until the quantityof oil is admitted to the said glass tube sufficient for a charge. Thevalve D is then closed. The globe-valve E' or both the globe-valves Eand are opened and the charge of oil is caused to pass into thesteam-pipe S, to be thence conducted to the parts of the engine tolubricate it.

Instead of opening the valve D to chargc the glass tube C, the valve D'maybe opened, whereupon the oil will pass down the pipe H and throughthe passage c c' ot' the lower fitting, B', into the glass tube G, andthen, upon the valve D' being again closed, the charge of oil in theglass tube O may be discharged into the steam-pipe by manipulation ofthe globe-valves E E', as before. Two ways of charging the glass tube Care thus provided, and if either one or the other set of passages fromthe oilchamber should from any cause become stopped the other set wouldprove effective.

If it is desired to suppl y the oil con tinuousl y from the oil-chamberto the steam-pipe instead of in charges, as described, this object canbe readily acconplished by leaving one or the other or both ot' theoil-valves D D', as well as one or both of the valves E E', openslightly, as will be readily understood.

In order to afl'ord as great a condensing-surface as possible withinconparatively small compass, I preferably corrugate the condenser eitherlongitudinally, as 'shown in Fig. 1, or laterally, as shown in Fig. 3.

The check-valve in the pipe F' is for the purpose ofpreventin g the oilfrom being all sucked out of the oil-chamber When theengineis work-` ingwith stean shut off, and is consequently producing a partial vacuum inpipe S. When steam is in the pipe S the cheek-valve opens and admits itinto the condensing-chamber; but when the steax is cut off with theengine still working the partial Vacuun formed in the pipe S causes thecheck-Valve to close, and all communication with the ol-chanber isthereby closed.

I claim as my invention 1. The eombination of the oil-chamber, thecondenser, and the pipe leading from the condenser into the oil-chamberwith the chargingtube C, having the upper and lower fittings, eachadapted to receive oil through {an overflow-passzge within theoil-chanber and discharge it into the charging-tuhe, and each alsohaving an independent passage leading.

to the steam-pipe, and with Valves for controlling the flow of oil intothe opposite ends of the charging-tube, and valves for controlling theflow of oil through the independent passages to the stean-pipe,substantially as described.

2. The combination of the oil-chamber, the condenser, and the pipeleading therefrom to near the bottom of the oil-ehamber with the upperand lower fittings, B B', their passages and valves, the vertical pipeconnected to the lower fitting within the oil-chamber, the glass charging-tube, and the globe-valves con neeted to the fittings and to thestean-pipe, substantially as described.
